A Bug in the Z21-1509H Maintenance

It recently came to our attention that under certain circumstances, attempting to use XDC in task mode FRR debugging causes the address space to hang at a pause. Turns out we had a bug in the Z21-1509H maintenance that allowed an incompatible TCB to be selected and used. This caused the “unpause” to never occur and things end up at a standstill.

Z21-1601B has been posted to address this issue. You can download the update from our Maintenance page.
